According to the Consumer Product Safety Commission, nearby activity during a fire can prevent the alarm from immediately sounding when the Nest Wave feature is enabled, which is intended to silence alarms with the wave of an arm. However, there have been no reports of any incidents thus far.

The recall affects all Nest Protect Smoke + CO alarms, which come in black or white with the word "nest" on a large button on the face of the alarm. They were sold at Best Buy, Home Depot and other retailers nationwide, as well as online at nest.com, amazon.com, bestbuy.com and homedepot.com from November 15, 2013 to April 3, 2014 for about $130.

Users who are connected to the wireless network should receive an automatic electronic update that disables the Wave feature.

Those who aren't connected are advised to do so immediately in order to receive the update, and to confirm with Nest Labs that their software is up to date.
